The spin Hall effect of light (SHEL) refers to the phe-nomena of beam splitting for circularly polarized light at some specific conditions, which has promising ap-plications in nanometric measuring, imaging and sens-ing. In general, the SHEL is very weak. Although the intensity can be increased by using resonant enhance-ment, the response bandwidth is limited. Recently, re-searchers from the State Key Laboratory of Optical Technologies on Nano-Fabrication and Micro-Enginee-ring, Institute of Optics and Electronics, CAS have demonstrated that single nanostructures with 2 μm dimension can generate broadband strong SHEL.
